BUTTER-COLLECTING APPLIANCE FOR CHURNS.

Specification of Letters Patent.

Patented Sept. 2'7, 191d.

Application filed June 8, 1910. Serial No. 565,804.

To all whom it may concern:

Be it known that I, SVEND HARTMANN, a citizen of the Commonwealth ofAustralia, and a subject of the King of Great Britain, residing at TheRialto, Collins street, Melbourne, in the State of Victoria, Australia,have invented certain new and useful Improvements in Butter CollectingAppliances for Churns; and I do declare the fol lowing to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to appliances or attachments to be used inconnection with rotary churns, for the purpose of collecting andremoving the butter therefrom.

The object of the invention is to provide an improved appliance forfacilitating the handling of the butter after the working of the samehas been performed.

The invention consists in the structure and combination of partssubstantially as hereinafter described and claimed.

Of the accompanying drawings :Figure l is a perspective view of a buttercollecting appliance constructed in accordance with my invention, theentrance end of a rotary churn of any suitable construction beingindicated by dotted lines. Fig. 2 represents a transverse section of theappliance on line 12 of Fig. 1. Figs. 3 and t are views similar to Fig.2, but illustrating slight modifications hereinafter described.

Similar reference characters indicate the same or similar parts in allof the views.

The appliance is capable of use in connection with any suitable form ofrotary churn, the axis of which is horizontal, such churn having theusual end door. In Fig. 1, the entrance door of such a churn isindicated at a by dotted lines. Churns of the rotary type mentionedusually have, as is well known, a butter working attachment, and alsodashers which carry the butter up and then drop it off toward the axisof the churn, after the worker is removed. My invention does not includeany such churn and dashers, nor butter worker, and therefore I haveomitted illustration thereof in order to avoid confusion. My inventionrelates solely to the means for collecting the butter and removing itfrom the churn after the butter has been worked.

The appliance includes a frame b mounted on suitable wheels so that itcan be moved about on a floor, said frame having standards b at one end,the collecting trough 0 being firmly connected at one end to the upperportions of the standards, said trough projecting rearwardly from thestandards, and having a closed rear end. Since there is a clear spacebetween the trough and the frame 6, the appliance can be run up to achurn and after the butter worker has been removed from the churn, thetrough 0 can be pushed in through the open door so as to receive butterwhich is elevated by the usual dashers of the churn, the butter slidingoff the dashers and dropping into the trough. The trough is preferably alittle more than semi-circular in cross sections, and is supported bythe standards Z), so that one edge is higher than the other. In theoperation of the rotary churn, the dashers are always rotated in a givendirection when the butter is to be elevated. The mounting of the troughis such that the opening or entrance to it faces toward that side pastwhich the dashers will move when rising. This results in the higher sideof the trough catching any butter that is sliding off the dashers.

In case the trough is not large enough to .collect all of the butter atone time. the

entire trough and the frame 6 would have to be removed away from thechurn, and then returned again to receive more butter. To avoidnecessity for removing the trough until the last of the butter has beenreceived therein, or in other words, to increase the removing capacityof the trough without having to shift it, I provide a tray (Z, which issuitably mounted on the continuous bottom of the trough, so that it cantravel in the direction of the length thereof. Said tray may be ofconsiderably less length than the trough, but it will receive a largequantity of butter. Usually the tray ill occupy a position near the rearportion g of the trough. lVhen the butter is piled thereon. the tray canbe drawn forward to the front end f of the trough, and taken out or thebutter can be taken therefrom, and then the tray pushed back to catchmore butter. Repeated operations of the tray enable all of the butter tobe brought to a readily accessible position for removing. Such butt-eras is not caught upon the tray will fall to the bottom of the trough.Since said bottom is continuous, that butter will remain there until theoperation has been finished, and the entire appliance removed from thechurn by shifting the frame 5 and drawing the trough out of the mouth ofthe churn. Of course the preferred material for the trough and the traywill be wood.

Secured to the bottom of the tray (Z I may employ wood strips 0 to slideon the bottom of the trough, as indicated in Figs. 1 and T he bottom ofthe trough may be provided with grooves 2 as shown in Fig. l, to guidethe strips 0. As shown in Fig. 3, 1 may provide rollers /z carried bysuitable bearings under the tray and adapted to travel on the continuousbottom of the trough. The tray (Z is preferably flat, and is made of asize to present the maximum area for catching the butter. When the trayis loaded, and has been drawn forward to the front end f of the trough,it tends to counterbalance the weight of the rear end of the trough.

I claim l. A butter collecting appliance for rotary churns, comprising atrough having a continuous bottom and provided with a. supportindependent of the churn whereby the trough may be moved into and fromthe churn, and a tray mounted to travel on the bottom of said trough inthe direction of the length thereof.

2. A butter collecting appliance for rotary churns, comprising a troughhaving a continuous transversely curved bottom, and provided with asupport independent of the churn and having a closed rear end and openfront end, and a tray mounted to travel on the bottom of said trough inthe direction of the length thereof.

A butter appliance for rotary churns, comprising a trough having acontinuous transversely curved bottom, and provided with a supportindependent of the churn and having a closed rear end and open frontend,and a tray mounted to travel on the bottom of said trough in thedirection of the length thereof, one side of the trough being higherthan the other.

el. A butter collecting appliance for rotary churns. comprising a troughhaving a continuous curved bottom, a wheel support for said trough, saidsupport and trough being connected together at one end, and leaving afree space between them rearwardly from the coi'niection, and a traymounted to travel on the bottom of said trough in the direction of thelength thereof.

In testimony whereof I have signed my name to this specifi 'ation in thepresence of two subscribing witnesses.
